His contributions to liturgical music in Rome were profound as composer, organist,
maestro di capella, writer on music theory and history, and as
esaminatori dei maestri for the
Academy of St. Cecilia. He was extremely prolific, with some 325 masses, 800 Psalm settings and 235 motets among the 3500 compositions listed by his pupil and biographer, Girolamo Chiti. He prepared a complete year of music for St. Peter’s, with settings for the masses and offices of every Sunday and holy day. Pitoni’s early works are brilliant examples of his genius in the Roman
contrapuntal style of Palestrina. In later years he moved toward more
homophonic textures with
polychoral elements. His use of
stile concertato also included solo sections and concertante instrumental parts. It is said that his immense facility allowed him to compose the parts of a 16-voice mass separately, without use of a score. To modern ears and eyes these compositions may seem dull and even repetitious. However, given typical performance practices in the early 18th century – vocal ornamentation ("
divisions"), instrumental participation,
antiphonal location for polychoral elements,
just intonation, and varied vocal colors – even the homophonic works must have made a strong impression in the highly reverberative church interiors of Rome. At the end of his life he was preparing a mass for twelve choirs, left incomplete at his death. He was buried in the Pitoni family vault in the
Basilica of San Marco, where he had served for some 66 years. His best known work is the
Dixit Dominus a 16 in 4 choirs. ==Music theory==
